Decided to give Signals a try and follow the current De-Fi hype… APY APY APY. So the idea is very simple: what is the annual percentage yield for a stock, based on its price and dividends?

I found a nice endpoint on IEX Cloud’s API: [https://iexcloud.io/docs/api/#dividends-basic](https://iexcloud.io/docs/api/#dividends-basic). The fields `amount` and `frequency`, combined with the daily price, being all we need.

IEX Cloud is free-ish, meaning there is a free account but it’s limited in endpoints and calls per month. However, they also provide a sandbox mode which you can call as much as you want. Some data in sandbox mode is obfuscated but not all. Also, a subscription for $9/month (~0.15NMR?!) is not the end of the world.

Anyway there’s two Python wrappers for the API: [https://github.com/addisonlynch/iexfinance](https://github.com/addisonlynch/iexfinance) and [https://github.com/iexcloud/pyEX](https://github.com/iexcloud/pyEX).

I was able to create a proof of concept for this APY signal and decided to open source it as an example script. Liam was actually so crazy to accept it into the official repo! [https://github.com/numerai/example-scripts/tree/master/signals/iexcloud](https://github.com/numerai/example-scripts/tree/master/signals/iexcloud)

Curious to hear if other Numeratis have experience with IEX Cloud. I am also very open to comments and feedback on the signal itself, so far the results for this rough version are not bad: [https://signals.numer.ai/gosuto\_test](https://signals.numer.ai/gosuto_test)

I was digging into yahoo finance this week and I believe they have all the data you speak of. They are also free. They have a python library, which I like. Thanks for sharing.
